How do you finish the edge of a anthracite corrugated sheet if it's cut at an angle on site? Regards Clive

Wipe the cut edge with a cloth to remove any metal shavings, dust, or debris. Apply a rust-resistant paint or sealant to the cut edge to prevent corrosion, especially if the sheet is exposed to the elements. Anthracite-coloured paint can help maintain the aesthetic. If the edge will be exposed to moisture or harsh conditions, consider applying a clear protective coating or anti-corrosion spray to further protect the metal.
